Should I keep going?

Hi everyone,
I just reached room 46 for the first time and I found the game quite nice!

Although some roguelike mechanics may get in the way of solving puzzles, I enjoyed the experience.

I still have a lot of things to find (I only have 1 red letter and many puzzles still to solve).

While starting the post game content, I ended up in the Gallery room.
After losing my mind on it, for the first time since I started the game, I looked online for some hint of the solution and I can safely say, as a non-native english speaker that I would not have been able to solve that in 1000 years.

That episode sort of led me to drop off the game. I don't want to look for solutions online, but if puzzles are going to be this hard (especially for people that know english as second language), I don't know if I can afford to keep going.

Even as a non-native speaker I had been able to solve the room pictures puzzles and I feel fine with that level of difficulty, but the gallery room was off the chart for me.

My question is: are there a lot of puzzles like that in the post-game or can I assume content similar to the rest of the game?
